#define UNPADDED_SIZE_MIN LZMA_VLI_C(5) |
Minimum Unpadded Size.
#define UNPADDED_SIZE_MAX (LZMA_VLI_MAX & ~LZMA_VLI_C(3)) |
Maximum Unpadded Size.
uint32_t lzma_index_padding_size | ( | const lzma_index * | i | ) |
Get the size of the Index Padding field. This is needed by Index encoder and decoder, but applications should have no use for this.
References lzma_index_s::index_list_size, index_size_unpadded(), LZMA_VLI_C, and lzma_index_s::record_count.
void lzma_index_prealloc | ( | lzma_index * | i, |
lzma_vli | records | ||
) |
Set for how many Records to allocate memory the next time lzma_index_append() needs to allocate space for a new Record. This is used only by the Index decoder.
